This post has appeared here for the last 4-5 days but with different numbers. The process of working it, however, is the same. In this case, onloy half the problem is posted.
Use the standard and Beer's Law to determine the constant a in A = abc. You know A, you know b (the cell length), and you can calculate c (from the problem).
I would start by determining mols Fe(NO3)3 and mols KSCN. You know they will form ?? mol FeSCN^+2. The final concn will be mols/L.
why is radioactive waste stored underground
is it because it is a harmful substance
Yes, it is harmful. It has long half lives and sticks around for 100s and 1000s of years (or longer). The idea of putting it underground is to use the earth plus man-made barriers (containers) to shield the radiation from the population. From what I've read, the project is far behind schedule, far behind in the technology, cost overruns are out of sight, and many of the temporary containers are starting to leak.
